Hello,

This series first extends the support for the Aspeed AST2500 and
AST2400 SMC driver. It adds Dual Data support and read training giving
the best read settings for a given chip. Support for the new AST2600
SoC is added at the end.

I understand that a new spi_mem framework exists and I do have an
experimental driver using it. But unfortunately, it is difficult to
integrate the read training. The Aspeed constraints are not compatible
and i haven't had the time to extend the current framework.

This patchset has been in use for some time in the OpenBMC kernel on
these systems :

 * OpenPOWER Palmetto (AST2400)
 * Evaluation board (AST2500) 
 * OpenPOWER Witherspoon (AST2500)
 * OpenPOWER Romulus (AST2500)
 * OpenPOWER Zaius (AST2500)
   and many others
 
and it is now in use on these boards with the new SoC :

 * Evaluation board (AST2600) 
 * Tacoma board (AST2600) 

Thanks,

C.
